Set the y scale before calling bar(). > - Each bar needs "centring" - they are arranged to the left of where I'd > like them to be currently. > - I'd like each of the ticks on the x axis centred beneath each of the bars. exp(0.1 + np.log(y)) I'm not sure I understand this. align=center might be what you want. > - I'm struggling to position text neatly above each of the bars - I've > managed to position text well horizontally but not vertically. The log scale > is making it hard for me to work out where to position them. If you write the text at y+k, then you'll see it log(y+k)-log(y) above the bar in the logarithmic plot. So if you want to see it h above the bar you have to write it at exp(h + log(y)). > - I'd like numbers in normal integer form not 10 to power form on the y > axis. I'm sure it can be done but I'm unable to help. Are you sure you want so many zeros in the Y tick labels? > Also how do I label each axis? xlabel(), ylabel() Also the calls to xticks() and plot() are useless.
